I have back problems and my doctors said that it could be worsening my IBS. There is a certain spot in my spine and really hurts(even to touch) and my doctors said taht that is the spot where the nerves for teh stomach and intestines go. I started seeing a chiropractor and he has been working on my back and my IBS has improved a lot. He is also a naturopath so i'm also taking supplements so that might also be contributing to me feeling better.But yes, i have heard this from my doctors(my internist and my neurosurgeon) too. SO for your friend it might help things but i dont' know if it would cure her IBS.
